1,3-Propanediamine, N'-(ethylcarbonimidoyl)-N,N-dimethyl-, monohydrochloride → 5,6-Difluoro-1H-indole-7-carboxylic acid (4-tert-butyl-benzyl)-[2-(3-trifluoromethyl-phenyl)-ethyl]-amide

Participants

Reaction Steps

87 mg (0.44 mol) of 5,6-difluoro-1H-indol-7-carboxylic acid, 134 mg (0.40 mmol) of (4-tert-butyl-benzyl)-[2-(3-trifluoromethyl-phenyl)-ethyl]-amine and 84 mg (0.44 mmol) of EDC.HCl were dissolved in 4 ml DCM. The reaction mixture was stirred at rt over night. The solvent was evaporated and the residue was purified by column chromatography (20 g silica gel; heptane/EtOAc 4:1) to yield 78 mg (38%) product as a colorless viscous oil. MS (ISP) 515.3 (M+H)+.
